Official effect

Wet-Only Stereo Wash

Runs each side through a compact comb-and-diffuser wash with no active dry blend control.

The current wash path is effectively wet-only, because the declared `mix` control is inactive and the signal is routed straight into one comb filter and one diffuser per channel. `width` sets the comb delay length, `motion` raises both the comb feedback and the diffuser delay, and `tone` opens the comb damping cutoff before the shared DC-blocking, output-gain, and soft-limiting stage.

How It Works

Technical view

The current wash path is effectively wet-only, because the declared `mix` control is inactive and the signal is routed straight into one comb filter and one diffuser per channel. `width` sets the comb delay length, `motion` raises both the comb feedback and the diffuser delay, and `tone` opens the comb damping cutoff before the shared DC-blocking, output-gain, and soft-limiting stage.

Effect core

Wet-only comb-and-diffuser wash applied per channel.

Signal path

The static waveform and the live player both reflect this compiled signal chain.

  • internal picked-string demo phrase
  • shared stereo spread with a short right-channel delay
  • per-channel comb resonator
  • per-channel short diffuser
  • DC blocker
  • output gain trim
  • final tanh limiter

Controls that matter

These are the currently active controls detected in the FAUST source for this effect.

  • mix: Declared in the shared control set but unused in the current preview code.
  • output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
  • width: Sets the comb delay length inside the wash network.
  • motion: Raises the comb feedback and the diffuser delay length.
  • tone: Sets the comb damping cutoff.

Code-backed analysis

The generated description is tied to the active helper blocks and routing found in the current DSP.

Controls

Audible controls in this DSP

  • mix

    Active

    Declared in the shared control set but unused in the current preview code.

    Changing it currently has no effect on the sound.

  • output_gain_db

    Active

    Applies final post-effect level trim after DC blocking and before the output limiter.

    Matches loudness without changing the underlying effect structure.

  • width

    Active

    Sets the comb delay length inside the wash network.

    Higher settings lengthen the resonant smear.

  • motion

    Active

    Raises the comb feedback and the diffuser delay length.

    Higher settings make the wash linger longer and spread more.

  • tone

    Active

    Sets the comb damping cutoff.

    Higher settings keep more upper-frequency detail in the wash.

Analysis

Code-derived notes

Current implementation is effectively wet-only because the declared mix control is inactive.
